You should switch off the ACC system:
• When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations (i.e.,
in highway construction zones).
• When entering a turn lane or highway off ramp;
when driving on roads that are winding, icy, snow-
covered, slippery, or have steep uphill or downhill
slopes.
• When towing a trailer up or down steep slopes.
• When circumstances do not allow safe driving at a
constant speed.
Adaptive Cruise Control (ACC) Operation
The speed control buttons (located on the right side of the
steering wheel) operates the ACC system.

WARNING!
Leaving the Adaptive Cruise Control (ACC) system
on when not in use is dangerous. You could acciden-

Always leave the system off when you are not using
it.
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the
SET+button or the SET -button and release. The DID
will display the set speed.
If the system is Set when the vehicle speed is below
20 mph (32 km/h), the Set Speed shall be defaulted to
20 mph (32 km/h). If the system is Set when the vehicle
speed is above 20 mph (32 km/h), the Set Speed shall be
the current speed of the vehicle. NOTE:
ACC cannot be set if there is a stationary vehicle
in front of your vehicle in close proximity.
Remove your foot from the accelerator pedal. If you do
not, the vehicle may continue to accelerate beyond the set
speed. If this occurs:
• The message “DRIVER OVERRIDE” will display in
the DID.
• The system will not be controlling the distance be-
tween your vehicle and the vehicle ahead. The vehicle
speed will only be determined by the position of the
accelerator pedal.

booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

WARNING!(Continued)
engine has started, ignite and damage the converter
and vehicle.
• If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
